The Walls of N’gogh

This city was once known as N’gogh, home of the dread wizard N’gogh’va. For centuries his ageless corpse lay buried, transfixed by a blade of meteoric iron – the only material that could penetrate his ensorcelled hide. It was by chance a foolish farmer stumbled on the wizard’s tomb and, seeking fortune, removed the blade from N’gogh’va’s corpse.
